Analgesia following day‐case knee arthroscopy—the effect of piroxicam with or without bupivacaine infiltration

Sixty patients presenting for day-case arthroscopy of the knee under general anaesthesia were studied. Patients were randomly allocated to receive, in addition to intramuscular piroxicam 20 mg, either bupivacaine 0.25% 20 ml applied locally to the knee at the end of the procedure (n = 30) or no further intra-operative analgesia (n = 30). Visual analogue pain scores were significantly lower at 1, 2 and 4 h postoperatively in the bupivacaine group (p < 0.05). A higher proportion of patients in the piroxicam-only group required supplemental analgesia before discharge from hospital. The combination of piroxicam and bupivacaine provided superior analgesia to piroxicam alone.
